Description of Related Art

The conventional hand-made circuit module used for teaching mainly contains a circuit board (a.k.a. breadboard), which is made of plastic material and configured with many holes on the surface. The pins of the electronic components can be plugged into the holes, and the copper wires can be provide to connect the components so as to form a circuit loop. In general, the copper wires and the electronic components are fixed by welding, winding, or clamping, thereby keeping the circuit loop on. However, the aforementioned fixing method is not only troublesome to operate and easy to loosen, but also may cause poor contact due to bad fixing operation. Therefore, the conventional hand-made circuit modules are easy to cause users' troubles in application, especially for people who have never contacted the circuit (e.g. non-professional or younger users). For example, the younger users may not finish the manufacturing of hand-made circuit module easily, and furthermore, the fingers of the younger users may be hurt by the copper wires or the pins of electronic components.

DETAILED DESCRIPTION OF THE DISCLOSURE

The present disclosure will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.

In the load adaptive device and hand-made circuit module including a load adaptive device of this disclosure, the electronic components of the load adaptive device can be arbitrarily replaced. The users can simply conduct circuits of the load adaptive device and the hand-made circuit module by attaching the hand-bonded adhesive tape, thereby reducing the difficulty of manufacturing the circuit board and allowing the user to intuitively and easily operate. Accordingly, the load adaptive device and the hand-made circuit module including the load adaptive device of this disclosure have the advantages of simple circuit, easy to manufacture, low cost and convenient to carry.

FIG. 1A is a schematic diagram showing a load adaptive device according to a first embodiment of this disclosure, FIG. 5A is a schematic diagram showing the electronic connection between the load unit, the power source unit, and the load adaptive device of FIG. 1A, and FIGS. 6A to 6C are schematic diagrams showing hand-made circuit modules according to different embodiments of the disclosure. As shown in FIG. 6A, this embodiment provides a load adaptive device 1 used for a hand-made circuit module 2 and cooperated with hand-bonded conductive tapes T1 and T2.

Referring to FIG. 1A, the load adaptive device 1 of this embodiment comprises a substrate 11, a first electrode 12, a second electrode 13, and a passive element 14. The substrate 11 is configured with a first conductor 111 and a second conductor 112. The surface area of the first conductor 111 and/or the surface area of the second conductor 112 are at least 15 mm², and the distance D1 between the center 1111 of the first conductor 111 and the center 1121 of the second conductor 112 is at least 9 mm. The first electrode 12 and the second electrode 13 are disposed on the substrate 11. The passive element 14 is disposed on a first surface 11 a of the substrate 11. In one embodiment, as shown in FIGS. 1A and 5A, the first electrode 12 is electrically connected to the first conductor 111, one terminal 14 a of the passive element 14 is electrically connected to the second conductor 112, and the other terminal 14 b is electrically connected to the second electrode 13. To be noted, referring to FIG. 1A, the conductive wires, conductive bodies or conductive blocks for electrically connecting the first electrode 12 to the first conductor 111, the terminal 14 a of the passive element 14 to the second conductor 112, and/or the terminal 14 b of the passive element 14 to the second electrode 13 can be disposed inside the substrate 11 and are not shown in FIG. 1A. FIG. 5A is only for illustrating the electronic connections between the above-mentioned components, and is not to limit the relative positions of the components. In addition, in the case cooperating with the hand-bonded conductive tapes T1 and T2, since the surface area of the first conductor 111 and/or the surface area of the second conductor 112 are at least 15 mm², the user can easily attach the hand-bonded conductive tapes T1 and T2 to the surfaces of the first conductor 111 and/or the second conductor 112. Accordingly, since the contact area thereof is larger, the conductivity therebetween can be improved. As shown in FIG. 6A, the dotted lines show the parts of the first conductor 111 and/or the second conductor 112, which are covered by the hand-bonded conductive tapes T1 and T2. Moreover, since the distance D1 between the center 1111 of the first conductor 111 and the center 1121 of the second conductor 112 is equal to or greater than 9 mm, the short circuit, which is caused by attaching the hand-bonded conductive tape T1 or T2 to contact both of the first conductor 111 and the second conductor 112, can be prevented.

In this embodiment, the surface area of the first conductor 111 and/or the surface area of the second conductor 112 are greater than or equal to 15 mm², and are less than or equal to 100 mm². According to this design, the user can easily attach the hand-bonded conductive tapes T1 and T2 to the surfaces of the first conductor 111 and/or the second conductor 112. Since the contact area thereof is larger, the conductivity therebetween can be improved. In addition, this design can also prevent the too large surface areas of the first conductor 111 and/or the second conductor 112, which may occupy too much space in the load adaptive device 1.

As shown in FIG. 1A, in this embodiment, the first conductor 111 and the second conductor 112 are disposed on the first surface 11 a of the substrate 11. In other words, the first conductor 111 and the second conductor 112 are disposed on the same surface (the first surface 11 a) of the substrate 11.

FIG. 1B is a schematic diagram showing a load adaptive device according to a second embodiment of this disclosure. As shown in FIG. 1B, in this embodiment, the first conductor 111 a and the second conductor 112 a of the load adaptive device 1 a are disposed on the first surface 11 a and the second surface 11 b of the substrate 11, wherein the second surface 11 b is opposite to the first surface 11 a. To be noted, the structure, components and function of the load adaptive device 1 a of the second embodiment are mostly the same as those of the load adaptive device 1 of the first embodiment. The difference between the first and second embodiments is in the configuration position of the first conductor 111 a or the second conductor 112 a. In FIG. 1B, since the first conductor 111 a is disposed on the second surface 11 b of the substrate, it cannot be directly observed in FIG. 1B and is shown by dotted lines.

FIG. 2A is a schematic diagram showing the cooperation of the load unit and the load adaptive device of FIG. 1A. Referring to FIGS. 1A and 2A, in this embodiment, the load adaptive device 1 can further comprise a load unit 15. The positive electrode of the load unit 15 is electrically connected to the first electrode 12, and the negative electrode of the load unit 15 is electrically connected to the second electrode 13. To be noted, referring to FIG. 2A, since the load unit 15 is disposed on the first electrode 12 and the second electrode 13, the first electrode 12 and the second electrode 13 are not shown in FIG. 2A. Moreover, in this embodiment, the load unit 15 can further comprise at least one load element 151, and the load elements 151 are electrically connected in series or electrically connected in parallel. Herein, the load unit 15 comprises one load element 151, and the load element 151 is, for example, an LED. To be noted, the load element 151 can be a buzzer, a speaker, a motor, a fan, an electrochromic sheet, an electric heater, or an electromagnet. Of course, the load unit 15 may comprise two or more load elements 151, and this disclosure is not limited.

In this embodiment, the passive element 14 is a resistor, and the passive element 14 and the load unit 15 are electrically connected in series.

Referring to FIG. 1A again, in this embodiment, an insulating area (shown as the dotted lines) is configured extending outwardly from outer peripheries of the first conductor 111 and the second conductor 112, and a width from the outer periphery of the first conductor or the second conductor to an outer periphery of the insulating area is at least 1 mm. Specifically, taking the second conductor 112 as an example, the second conductor 12 is a circular sheet structure, and the distance from the center 1121 to the periphery of the second conductor 112 is defined as the radius r of the second conductor 112. The insulating area (dotted lines) is located extending outwardly from the outer periphery of the second conductor 112, and the center of the insulating area is overlapped with the center 1121 of the second conductor 112. The outer radius of the insulating area is equal to the sum of the radius r of the second conductor 112 and the width D2 of the insulating area (the distance from the outer periphery of the insulating area to the outer periphery of the second conductor 112). Wherein, the width D2 is at least 1 mm. In other words, the outer periphery of the insulating area can be defined as the range extending outwardly from the outer periphery of the first conductor 111 and the second conductor 112 for at least 1 mm. Accordingly, the short circuit, which is caused by attaching the hand-bonded conductive tape to contact the other elements of the load adaptive device 1 (e.g. the first electrode 12, the second electrode 13, or the passive element 14), can be prevented.

FIGS. 3A to 3C are schematic diagrams showing different aspects of the first conductor and the second conductor in the load adaptive device of this disclosure. Referring to FIG. 1A in view of FIGS. 3A to 3C, each of the first conductor and the second conductor can be a circular sheet structure, a triangular sheet structure, a rectangular sheet structure, or a polygonal sheet structure. As shown in FIG. 1A, the first conductor 111 and the second conductor 112 of the load adaptive device 1 are circular sheet structures. As shown in FIG. 3A, the first conductor 111 c and the second conductor 112 c of the load adaptive device 1 c are triangular sheet structures. As shown in FIG. 3B, the first conductor 111 d and the second conductor 112 d of the load adaptive device 1 d are rectangular sheet structures. To be noted, the shape of the rectangular sheet structure can be a square as shown in FIG. 3B, or any rectangle (quadrilateral) shape. As shown in FIG. 3C, the first conductor 111 e and the second conductor 112 e of the load adaptive device 1 e are polygonal sheet structures. To be noted, the shape of the polygonal sheet structure can be a hexagon as shown in FIG. 3C, or any polygonal shape (e.g. pentagon, heptagon, octagon, etc.). This disclosure is not limited. In addition, the first conductor and the second conductor can be sheet structures in different shapes, which have the surface areas between 15 mm² and 100 mm², so that the user can easily attach the hand-bonded conductive tape. This disclosure is not limited thereto. The structures, components and functions of the load adaptive devices 1 c, 1 d and 1 e are mostly the same as those of the load adaptive device 1 of the previous embodiment, and the differences therebetween are in the shapes of the first conductors 111 c, 111 d, 111 e and the second conductors 112 c, 112 d, 112 e.

In this embodiment, the substrate 11 is a PC substrate, such as, for example but not limited to, the aluminum substrate, iron substrate, paper phenol copper laminated substrate, paper epoxy copper laminated substrate, glass-epoxy copper laminated substrate, glass composite copper laminated substrate, glass-epoxy substrate or glass-phenyl resin substrate. Alternatively, the substrate 11 can be a flexible substrate such as, for example but not limited to, a paper substrate, a rubber substrate, a wood substrate, a bamboo substrate, a cotton substrate, a high-density fiber substrate, or any combination thereof. Preferably, the substrate 11 is a paper substrate or a rubber substrate.

FIG. 4A is a schematic diagram showing the second surface of the substrate in the load adaptive device of FIG. 1A, and FIG. 4B is a schematic diagram showing the second surface of the substrate in the load adaptive device of FIG. 1B. As shown in FIGS. 1A, 1B, 4A and 4B, in this embodiment, the second surface 11 b of the substrate 11 is coated with an adhesive layer P, and a release film M attaches to and covers the adhesive layer P. Referring to FIGS. 1A and 4A, the first electrode 12, the second electrode 13, the passive element 14, the first conductor 111 and the second conductor 112 are all disposed on the first surface 11 a of the substrate 11, and the second surface 11 b of the substrate 11 is coated with the adhesive layer P. The release film M is disposed on the adhesive layer P. In practice, the user can peel the release film M off the adhesive layer P, and then attach or stick the substrate 11 at any position through the adhesive layer P, thereby applying to the hand-made circuit module. Referring to FIGS. 1B and 4B, the first electrode 12, the second electrode 13, the passive element 14, and the second conductor 112 a are all disposed on the first surface 11 a of the substrate 11, and the first conductor 111 a is disposed on the second surface 11 b of the substrate 11. The second surface 11 b of the substrate 11 is coated with the adhesive layer P, and the release film M is disposed on the adhesive layer P. In practice, the user can peel the release film M off the adhesive layer P, and then attach or stick the substrate 11 at any position through the adhesive layer P, thereby applying to the hand-made circuit module. Particularly, as shown in FIG. 4B, the adhesive layer P is disposed on a part of the second surface 11 b other than the position of the first conductor 111 a, thereby avoiding to reduce the conductivity of the first conductor 111 a. To be noted, the application examples of the applying the load adaptive device 1 or 1 a to the hand-made circuit module through the adhesive layer P will be described hereinafter. Moreover, FIGS. 4A and 4B show that the release film M is only partially bonded to the adhesive layer P, which indicates the procedure of peeling the release film M off the adhesive layer P. It should be understood that the release film M completely covers the adhesive layer P before the user peels the release film M off. When the user intends to attach the load adaptive device 1 or 1 a to an object (e.g. the hand-made circuit module), he/she can start to peel the release film M off the adhesive layer P and then attach the load adaptive device 1 or 1 a to the object through the adhesive layer P.

FIG. 2B is a schematic diagram showing the cooperation of the switch element and the load adaptive device of FIG. 2A. As shown in FIG. 2B, the load adaptive device 1 of this embodiment further comprises a switch element 18, which is disposed on the substrate 11. The switch element 18 is electrically connected to the load unit 15 or the passive element 14 in series. To be noted, the conductive wires, conductive bodies or conductive blocks for electrically connecting the switch element 18 to the load unit 15, or the switch element 18 to the passive element 14 can be disposed inside the substrate 11 and are not shown in FIG. 2B. In this embodiment, the switch element 18 is a ball switch.

Referring to FIG. 5A, in this embodiment, the load adaptive device 1 can further comprise a power source unit 16. The positive electrode 161 of the power source unit 16 is electrically connected to the first conductor 111, and the negative electrode 162 of the power source unit 16 is electrically connected to the second conductor 112. For example, the load element 151 of the load unit 15 of the load adaptive device 1 is an LED. In this case, the load unit 15 of the load adaptive device 1 can be turned on (lighted up) after electrically connecting the power source unit 16 to the first conductor 111 and the second conductor 112. To be noted, as shown in FIG. 5A, since the load unit 15 is disposed on the first electrode 12 and the second electrode 13, the first electrode 12 and the second electrode 13 are blocked and are shown by dotted lines.

FIGS. 5B and 5C are schematic diagrams showing the electronic connections between the load unit, the power source unit, the charge-discharge control unit, and the load adaptive device of FIG. 1A. Referring to FIGS. 5B and 5C, the load adaptive device 1 of this embodiment further comprises a power source unit 16 and a charge-discharge control unit 17. The negative electrode 162 of the power source unit 16 is electrically connected to the second conductor 112 through the charge-discharge control unit 17, and the positive electrode 161 of the power source unit 16 is electrically connected to the first conductor 111.

In this embodiment, the charge-discharge control unit 17 comprises a transistor 171 and a charge-discharge loop 172. The transistor 171 comprises a third electrode 1711, a fourth electrode 1712, and a control electrode 1713. The third electrode 1711 is electrically connected to the second conductor 112, the charge-discharge loop 172 is electrically connected to the control electrode 1713 and the fourth electrode 1712, and the negative electrode 162 of the power source unit 16 is electrically connected to the charge-discharge loop 172 and the fourth electrode 1712. The transistor 171 can be a bipolar junction transistor (BJT), a field effect transistor (FET), or an insulated gate bipolar transistor (IGBT). The field effect transistor includes a junction field effect transistor (JFET) or a metal-oxide-semiconductor field-effect transistor (MOSFET). In this embodiment, the transistor 171 is, for example, an N-type MOSFET. Thus, the control electrode 1713 of the transistor 171 is the gate G of the MOSFET, the third electrode 1711 thereof is the drain D of the MOSFET, and the fourth electrode 1712 thereof is the source S of the MOSFET. In another embodiment, the control electrode 1713 of the transistor 171 is the gate G of the MOSFET, the third electrode 1711 thereof is the source S of the MOSFET, and the fourth electrode 1712 thereof is the drain D of the MOSFET. The skilled person in the art should understand the three electrodes of different types of transistors, so the detailed descriptions thereof will be omitted. Particularly, referring to FIGS. 5C and 6C, the charge-discharge control unit 17 can be configured with a third conductor 17 a, a fourth conductor 17 b, and a fifth conductor 17 c, wherein the third electrode 1711 is electrically connected to the second conductor 112 through the fourth conductor 17 b, the negative electrode 162 of the power source unit 16 is electrically connected to the charge-discharge loop 172 and the fourth electrode 1712 through the third conductor 17 a, and the fifth conductor 17 c is electrically connected to the charge-discharge loop 172 and the control electrode 1713. To be noted, the load adaptive device 1 can transform the first conductor 111 and the fifth conductor 17 c into an active switch through the charge-discharge control unit 17. In practice, when the first conductor 111 and the fifth conductor 17 c are conducted (e.g. by finger F), the load unit 15 (e.g. comprising LED (the load element 151)) can be turned on (lighted up). To be noted, since the load unit 15 is disposed on the first electrode 12 and the second electrode 13, the first electrode 12 and the second electrode 13 are blocked and are shown by dotted lines.

In this embodiment, the charge-discharge loop 172 includes a capacitor C and a resistor R, which are connected in parallel. The capacitor C is an electric storage element, and the RC parallel circuit has a time constant τ(τ=R*C). This value τ determines the change rate of the electricity quantity of the capacitor C. The larger the time constant τ, the slower the electricity change, and the longer the charging and discharging time. On the contrary, the smaller the time constant τ, the faster the electricity change, and the shorter the charging and discharging time. In other words, the function of the charge-discharge loop 172 of this embodiment is similar to a timer, which controls the charging and/or discharging time by controlling the capacitance and/or resistance thereof, thereby controlling the operation and/or stop time of the load unit 15. For example, the charge-discharge loop 172 can control the On/Off time of the LED(s). In a different embodiment, the charge-discharge loop 172 can comprise a capacitor C only. The load unit 15 may comprise a plurality of load elements 151 (e.g. LED circuits or other electrovariable elements), which are connected in series and/or in parallel, depending on the circuit design requirement. In some embodiments, when the load unit 15 comprises a plurality of LEDs, which are connected in series, the multiple LEDs can be controlled to be turned on/off simultaneously. In other embodiments, when the load unit 15 comprises a plurality of LEDs, which are connected in parallel, the multiple LEDs can be controlled to be turned on/off sequentially.

Referring to FIG. 1A, the load adaptive device 1 can further comprise a plurality of marks, which are disposed on the first surface 11 a of the substrate 11 and located adjacent to the first conductor 111, the second conductor 112, the first electrode 12, and/or the second electrode 13. In this embodiment, the marks can be, for example but not limited to, “power +”, “power −”, or “load”. Wherein, “power +” represents the positive electrode of power source, “power −” represents the negative electrode of power source, and “load” represents the load (i.e. load unit). According to these marks, the user can realize that the first conductor 111 need to be electrically connected to the positive electrode 161 of the power source unit 16, and the second conductor 112 needs to be electrically connected to the negative electrode 162 of the power source unit 16, and the first electrode 12 and the second electrode 13 need to be electrically connected to the load unit 15. In practice, when the first conductor 111 and the second conductor 112 are electrically connected to other elements through the conductive tape, if one of the marks is blocked by the conductive tape, the user can still realize that the conductor (the first conductor 111 and/or the second conductor 112) needs to be electrically connected to which element(s) based on the other uncovered marks.
